List marketplace services

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden, yet it discloses nothing about permissions, pagination, whether the list is filtered/active-only, or what the result looks like. It is a tautology with a parameter echo.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is short and front-loaded with no padding, but that brevity stems from under-specification rather than efficiency — nothing substantive is communicated.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations, no output schema, 0% parameter coverage, and four-plus similarly named siblings, the description supplies essentially none of the context needed to select or invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and the single parameter is an untyped-in-practice integer with no description; the text only names 'marketplaceId' without explaining format, source of valid IDs (e.g., from list_marketplaces/get_owned_marketplaces), or required scope.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description merely restates the tool name (list marketplace services) plus the parameter name, adding no scope, output, or differentiation. An agent cannot tell from this text how it differs from siblings like get_available_services_for_marketplace or get_possible_services_for_parent.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool, when not to, or which of the many service-listing siblings is the alternative. The existence of at least three similar service/marketplace tools makes this omission costly.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
